You know, one thing that I hope that we get to see in a few more interactions between Thor and Erik Selvig. That was one thing that I had wished that we had seen more of in "The Avengers", but I understand why there wasn't enough time to deal with that. Still, it would have been nice to see their interactions post Erik witnessing what Thor could really do and how he was telling the truth about his identity back in the first film.

If they had allowed the events in "Thor" to have taken place from a span of a few months as opposed to just 3 days, Erik could have even been used imho as a good surrogate father figure for Thor (despite their huge age differences.lol) on Earth.
